A better understanding is needed of the clinicopathologic features of metastatic melanoma and, in particular, of its rare manifestations. Case Report: A 33-year-old woman with a past medical history of malignant melanoma presented with symptoms of throat discomfort and bleeding. On physical examination, a dark pigmented lesion was observed on the right tonsil. Tonsillectomy was performed, and melanoma was diagnosed. Computed tomography of the thorax and abdomen revealed a filling defect in the right atrium and a 4-cm gallbladder mass. Echocardiography revealed a right atrial mass. No further metastasis was detected by whole body (18)F-fluorodeoxyglucose positron emission tomography. Each metastasis was completely resected with clear margins. The pathologic diagnosis of the resected masses was malignant melanoma. 3 weeks after the final surgery, temozolomide was started. The patient has been followed up for 9 months after diagnosis of the first recurrence, and no new metastases have been detected. Conclusion: We report a case with synchronous tonsil, gallbladder, and heart metastases without any other common sites of metastasis of melanoma. The patient was successfully treated with aggressive surgery followed by temozolomide.en10.1159/000201126info:eu-repo/semantics/closedAccessMalignant MelanomaTonsilGallbladderHeartSurgeryArticle324197199Q4WOS:0002651304000082-s2.0-6534908444019372715N/A
